Nit-picky Winter Soldier ramblings

So I was perusing the Captain America Message Board over at Comicboards, as I do occasionally. And I posted a reply to a thread, as I do very rarely--but someone had asked a question, wondering how old the Winter Soldier was, and I realized that I had figured that out at some point from the comics. So, because the Comicboards posts disappear pretty quickly, I'm noting my logic here, so I can find it easily:

Well, he was (I think) 20 when he disappeared (the 65th Anniversary Special states that he had just turned 19 in April of 1944, and according to Cap #8, Karpov's sub found him in April of 1945), so that's the starting point (Cap would have been about 24 then, since Cap #12 says that he's 4 years older).

After he was revived they kept him active for about three straight years (June '54 through June '57, from Cap #11) before they started keeping him in stasis in between missions. So that makes 23.

When Karpov was at the end of his career, he took WS as his personal body guard starting in September '83. We can probably assume he was out of stasis for all of the time Karpov was using him, because he wouldn't be much of a bodyguard otherwise. He's returned to stasis in August of '88, after Karpov's death, so that's almost five more years. That makes 28.

Other than that it's hard to say because he would have aged in bits and pieces when on missions, and held in stasis otherwise, so it would depend on the number of missions and how long they took. Most were probably fairly short (maybe a few weeks?) although didn't he say he had been out for a period of months trying to get to Wolverine? (Can't locate the pertinent issue of Wolverine at the moment, so I'm not sure.) So he could be older than Cap, although unless it's specifically stated there's no way to be sure. I'd certainly place him at least late 20s-early 30s.

I think I'm pretty close to right, there. I didn't count any of the time that's passed since he appeared in Captain America a few years ago, because that's comic time and it's very flexible (if forty real-time years equals ten comic-time years, I wouldn't begin to guess how much time has passed in the Marvel Universe since even House of M happened) and therefore not at all helpful in figuring this stuff out. The historical info in Cap's book, though, that's got specific dates, that's as solid as you can find in comics.

I'm not sure why I noticed this in the first place, except that it means that Bucky was the Winter Soldier for at least twice as long as he was Cap's sidekick, probably longer. He's got more experience in that role, he's spent more time in it, he has more memories (presumably) of that life.
